dumps are included and are playable and have been tested successfully on
the emulator EmuZ-2000. To start the game you'll first need to load the
MZ-1Z002.dat included here as a tape. Once that has booted you'll need
to load one of the Door Door WAV files then type LOAD and hit enter. After it loads it will be a blank prompt and you simply type RUN to start the game.
